To all whom it may cancer 22 5 Be it known that I, SAMUEL Levin, oisizen of Russia, and resident oi iiew York city, borough of Brooklyn, inthe county of 5 Kings and State of New York, have invented certain newand useful improvements in Hose Couplings, of which the 'foiiowing is aspecification.

The object of my invention is to provide hose coupling of such characterthat it may be securely attached to hose and be readily removed Withoutinjury to itself or to hose, and wherein the hose gripping element is111 integral part of one of the'inein cou pling members so that saideiement member will ziiwu ys remain united.

in carrying out my invention I provide 2. main coupling member having. apiiabie spirsi hose-gripping element integral with said member toreceive a hose, and another coupling member to compress the spiralmember on the hose, with means cooperative between said members todetzichshiy unite thein and cause the second named member to force thespiral eiement against the hose.

My invention also comprises novei deta ls of improvement that Wiii hemore fniiy here inzifter set forth and then pointed. out in the cisims'Reference is to be hst to the seems-sen ing drawings fox-ailing perthereof.

The member 1 is shown with the nut-like part 1 at the end oppositeelement 1 to receive a Wrench, the member 2 likewise having flats 2 fora wrench.

My improvement is simple in construction, efiective in use, not liableto damage or to get out of order, and cheap to manufacture.

Havingnow described my invention, what I claim is I l. A hose couplingcomprising a member having a pliable spiral element integral therewithat one end and free at the outer end, another member to fit over saidelement to force it against a hose, and means to secure said memberstogether;

2. A hose coupling comprising a member having a pliable spiral elementintegral therewith at one end and free at the outer end, another memberto fit over said element and having a bore provided with a tapering faceto force said element against a hose, and means to secure said memberstogether. 3. A hose coupling comprising a member having an integralspiral pliable element at recessed case member, a ferrule enclosing ahose end and entering said case member, and,

a pliable spiral element cooperating with said ferrule and adapted to bepositively r0"- tated and forced against the hose when the case memberand ferrule are secured together.
